I have a new Esplora board and IDE v1.0.5I have selected the Blink Sketch and tried to upload it. But I get a message about being unable to upload to a Leonardo on the selected port. I understand the Esplora is based on the Leonardo so I followed the instructions about pressing the reset button first. The "On" and "L" LEDs light up, but no Tx/Rx

I checked the port is active by switching to the Uno (rev2) and using the blink sketch on that. No problems.

I feel so stupid. After hours of research and faffing about I went to play with the RaspPi, trying to use SSH or VNC. This tied up the USB lead I was using.

"I'll have one last try", I thought, and grabbed the cable for my Kindle. Up popped the message about an unrecognised keyboard being connected. Off to load Arduino IDE (1.0.5) and everything is working.
